Yes, I'm obsessed. I can't stand vocal mics being directly in front of
the
mouth. Three reasons:
1) Mic pops: The air that puffs out on the letters P and B (and T and C to a
lesser extent) pops the microphone in an ugly manner (even at quite a
distance).
2) There's often not enough nose in the sound, so it gives the singer
that slightly blocked nose sound, losing the Ms, Ns and NGs.
3) It covers up the mouth so you can't see what's going on.

The solution?
The Cindy Crawford Mole Position!

Yes, moving the mic to one side a little (somewhere around the corner
of the mouth), angled in (aiming diagonally back towards the
lips) and slightly up, will solve all these problems: The pops can go
past, nasal component is added and you can see the mouth... yay! What's
more, when you sing louder, try moving the mic around your face a
little rather than away: This means the warmth (low
frequencies) aren't lost as you get louder. This is easy if the mic is
on a stand... just turn your head away from the mic.
People often complain they sound weird through a mic and this is mostly
because you naturally hear yourself through your head (via the
estacean tubes, etc.), so the nasal component of your voice is an
important part of you
sounding like yourself.

Now, getting singers (and speakers) to do this is a challenge, as we're
all obsessed with symmetricality. But several renowned audio engineers
I know have confirmed that most people don't sing symmetrically anyway.
And if you play an asymmetrical instrument (like guitar, bass, drum
kit, accordian, hurdy gurdy, etc), it's not going to seem strange to
the audience. Most piano players mic the voice from the side anyway.
And if you're
holding the mic in one hand, as most singers do (well, except Chrissy
Amphlett), it's more comfy to have it to one side.

So, give it a go!
Challenge convention... just because people have been eating mics for
as long as mics have been around, doesn't mean it's the right thing to
do.

Extra note: The chin position is OK for speakers and comedians, because
at that distance, the mouth/nose mix is fine, but because of the
distance, the mic has to be turned up louder and thus it's no good for
band situations. And unfortunately, many people let it drift up into
the pop zone (which is lower than you might think), and that's extra
bad, due to the fact the level is pumped up and the EQ is made bassier
to counteract the distance... aarrgghh, pop-o-rama! People just have to
get over the symmetry thing, as the sound doesn't care. An off centre
chin position (like, in jowl position), is ideal for speaking gigs, as
it still leaves the mouth visible to all, but let's you bring it a up
closer without the risk of popping.

Smith having only recently learnt the joy of the CCMP.
